35mm prop 1s concept

This is more of a proof of concept more than anything. Sort of reminds me of my old Leader 120. I wanted to make a real basher since I have mostly hardwood and tile floors. All CF is 2mm thick, and despite using as few components as possible, total dry weight is 27.2g, so a bit heavy. I've changed the design to the CF parts to lighten it a bit and to use 1.5mm side plates, theoretically saving me 2g, not sure if it will be enough weight difference. So for now, not sure how/if i want to progress on this concept.

Using betafpv 1s aio with spi frsky rx and built in vtx. Note in betaflight if upgrading to latest version: After applying custom defaults I had to change gyro alignment to CW 90 flip. Also, documentation on this FC says it has O_L_5 escs, however when connected to Jesc configurator or Blheli configurator the escs identify themselves as O_H_5. I have Jesc 2.3 with rpm filter for O_H_5 escs running on it currently with no issues. Frsky SPI rx is in D8 mode since I was getting dropouts in D16.

Waaaay to heavy. If you're not around 20g for 1s 31mm props you're doing something wrong. If you want to go for looks, I'd recommend 2s on 40mm props so that the thrust to weight ratio isn't destroyed.

Yeah its pretty heavy, i was thinking about changing it to fit 40mm or 2 inch props. Even though this build didnt turn out how i wished, i feel like its still important to share failures in the hopes someone can learn from my mistakes

FPV has had quite a journey. Just a few years ago we started racing drones around a track and doing flips over trees, but professional cinematic FPV is a more recent development. DJI has always owned the drone photography market, but smaller acrobatic drones are starting to enter the market. They have the advantage of close proximity flight indoors and around people. There's more artistic freedom and..

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..
